is this possible to get index of foreach loop in c#?

Question

i want to update my db table with foreach loop and what i need is to get index of foreach loop to get right index of declared array to sum with count of my db.

byte[] OldSelectedProductsCount = ThisFactor.BuffetServices.Where(q => q.FactorID == ThisFactor.FactorID).Select(q => q.Count).ToArray();

giveBackBuffets.ForEach(t => _Buffet.Update(new BuffetViewModel()
{
    BuffetID = t.BuffetID,
    Name = t.Name,
    Price = t.Price,
    Count = t.Count + OldSelectedProductsCount[idexofforeachloop],
 }));

Answer 1

You can try this instead of the foreach loop

    byte[] oldSelectedProductsCount = ThisFactor.BuffetServices.Where(q => q.FactorID == ThisFactor.FactorID).Select(q => q.Count).ToArray();

    for (int i = 0; i < giveBackBuffets.Count; i++)
    {

        _Buffet.Update(new BuffetViewModel()
        {
            BuffetID = giveBackBuffets[i].BuffetID,
            Name = giveBackBuffets[i].Name,
            Price = giveBackBuffets[i].Price,
            Count = giveBackBuffets[i].Count + oldSelectedProductsCount[i],
        });
    }
